rIEE-EscArE.

To all whom it mag concern:

' Be it known that I, HENRY SPERLING, acitizen of the United States, anda resident of West Hoboken, in the county of Hudson and State of NewJersey, have invented certain new and useful Improvements in'Fire-Escapes, of which the following isaspecification. v

This invention. relates to a fire-escape of the class described inLetters Patent No.

693533 issued to me February 18th, 1902.

The object of the present invention is to provide new and efficientmeans by which the raising of the ladders is facilitated; so that theoperating Winches are relieved of excessive strain.

In the accompanying drawing: Figure 1 is a side elevation of my improvedfireescape showing it folded; Fig. 2 a similar view showing itraised;Fig. 3 a detail of a portion of the lower post and ladders; Fig. 4 aplan with the post and ladders removed, and Fig. 5 a longitudinalsection through one of the tubular lifting rods and adj oining arts. pThe device comprises essentially, a platform 1 mounted upon .wheels 2 toconstitute a truck. Upon platform 1 is rigidly fitted,

a base 3 to which is hinged. at 41, a lower post 5. To the upper endof-this post there is hinged at 6, an upper post 7, the hinges 4 and 6being located respectively at the rear and front of the apparatus. Eachof the posts 5 and 7 is furnished with a plurality of landings 8 whichare connected by a series of rear ladders 9 and a series of extensibleside ladders 10. The latter are hinged to the landings 8 and may belowered into a horizontal position so as to rest with their free endsupon the window sills. In addi tion to the side ladders 10, the postsmay also carry one or more bridges or gang-planks 11 indicated in Fig.3. Posts 5 and 7 after being raised, may be locked in their uprightposition by bolts 12 and 13 respectively.

To the upper side ofthe upper post .7, longitudinally the periphery ofthe arch by eyes 18. The front rope 16 passes from the hinged end of thearch to a winch 19 located at the front of the truck, while the rearrope 17 passes from the free end of the arch through a guide 20 to awinch 21 located at the back of the truck. A rest 22 projecting upwardlySpecification of Letters Patent. Pa tented N 30, 1915. Application filedSeptember 18, 1915. Serial No. 51,309. I I i post'5, there isprovided, alifting jack or post composed of a tubular member 23 that telescopesa-rod 24. .As more fully referred to in Patent 6923533, tubularmember 23is provided with a roller 25 engaging a rail by a rope 27 leading to awinch 28. Rod

24 is hinged to post 5 at 29 and may be projected out of tube 23 bymeans of a rope 30 which is secured to lower end of rod 21 and p 26 andadapted to be moved along the same passes over an idler 31 to a windingdrum 32 carried by tube 23.- It will be seen that by operating winch 28,the lowerend of the jack will be moved toward the back of plat form 1during which movement it will become partly righted so as to impart anin'i-' tial lift to post '5. By then operating drum 32, rod 241 will 'beprojected upward to. push said post into an upright position, in whiclr,

itisheld by locking bolt 12.

Novel means are provided for so swinging the upper post 7 that it willbe carried into an approximately vertical position prior to themanipulation of winch 21, so that in this way, the power andtimerequired for operating the winch and the strain to which the same issubjected, are greatly reduced.

These means are as follows: Along each side of platform Lextends a track33 engaged by a roller34 pivoted to the lower end of a tubular rod 35 Toeach rod is secured, a rope 36 the two ropes being wound on a pair ofdrums 37 carried by the common shaft 38 of awinch 39. To rods 35 arepivoted a pair of props 10, which will by gravity, tend to assume averticalposition, and thus hold 1 i the rods in an inclined position,when moved forward along track 33. uuy ropes 41 at tached to onerof theupper platforms 8 of post. 5, and adapted to be detachably secured tothe upper ends of rods 35, prevent the latter from dropping down, afterhaving been raised to such 'a height, that props. 1O have lost theirfooting. f p

The two rods 35, telescope the two shanks 42 of an inverted U-shapedyoke or frame, said shanks being connected'together at their upper orprotruding ends by across 19:11:43. This cross bar is furnished at itscenterwith apulley 41, adapted to removably engage a I hook 45 extendingforwardly from the upper end of upper post 7. In order to operate theyoke, there is secured to the inner end of each shank 4E2, a rope 16,passing ever an idler 47 of rod 35, and thence to a Winding drum 4:8with which said rod is provided. A feather 4:9 on shank 42 that engagesa corresponding groove 50 o'f rod 35, guides the yoke in a properrectilinear direction While it being inoved. H r

After the lower post 5 has been ri'ghted the manner above described,Winch 39 o'p'- erat'ed to advance rods 35 along tracks 33', and therebycause an initial lift to be inr parted to 'iip'per post 7; The guy ropes41: are now attached to rods 35, and then inch druins 48 are operated toproject the-yoke out or the rods, and thuscause the'sani'e impart anadditional and Very substantial lift'to post T, so that the sa111ease11111 s almost an upright position. Finally, ivir rch 21 is operatedto coinpletelthe righting of the post, it being locked in its uprightposition by bolt 13. r H I As shown the entire structure 'be steadied bya pair'o'f ropes orcha ins 51 that are secured to one of the upperplatforms of lower post 5, and are adapted-to be connected to hookslocated at the forward doiners of platform 1. V

In order to lower thedeyice, boltl'i-B is released, which 19 is operatedto pull r pper post 7 down, so that its hook'd5 is reenga'ged by pulley44. Drum s are new manipulated to lower the yoke aiidtli'en Winch 39 isturned back to slacken ropes 36 and thus permit rods 35 to be, bygravity, retracted along tracks 33 so as toassunie their foldedposition. v A buffer 52 projecting from lower pcst 5 and adapted tonpper post 7, prevents a iolent contact during the folding operation;After'the upper pcst has been folded, bolt 12 is retracted and thenlower post 5 is folded i ponrest 2 2 while simultaneously, tube 23 isnioved along rail 26, and rod 24 is telescoped so that in this way allthe parts resume the position shown in full lines Fig. 1.
